In the home center, one of the same size is sold for about 500 yen, so I think that this is a bargain. Since it is wrapped in vinyl one by one, it is in a paper box, so I wonder if I can keep some of them. When exchanging, I struck the shaft on the bearing with a hammer, but it seems no problem.

Miyata's unicycle is attached from the beginning NACHI 6203 ZE It is also inferior in smoothness of rotation but can also run and idling etc. as usual. I do not know how to play with a unicycle for competition but as a ride with a hobby, there is no problem for now.
